Q How do I recognise blossom wilt of pears?

A In blossom wilt of pears, the blossom turns brown and dies shortly after opening, yet remains on the tree. The infection often spreads into the adjacent leaves, which also turn brown and die, causing localised dieback. Look really closely using a magnifying glass and you can see pinprick-sized, raised, buff-coloured pustules on the infected areas; the spores are shed from these and cause more infections. 

Q How can I help pear trees that are infected with blossom wilt?

A Prune out infected flower trusses, ideally before the leaves or spur are affected.

Q How can I prevent blossom wilt affecting my pear tree?

A Wet conditions and poor air circulation encourage the spread and development of the symptoms, so try to ensure that trees aren’t congested with branches or overshadowed by other plants so that air circulates freely.
